Memory
This menu offers options to change the memory settings.
| Item | Options | Description |
|---|---|---|
| System Memory Details | N/A | Displays status of the system memory. |
| Total Usable Memory Capacity | yyyy GB | Displays Total Usable Memory Capacity. |
| Memory Speed |
| Selects the desired memory speed. [Maximum Performance] maximizes performance. [Balanced] offers a balance between performance and power. [Minimal power] maximizes power savings. When a preset mode is selected, the low-level settings are not changeable and will be grayed out. To change the settings, choose System Settings > Operating Modes > Choose Operating Mode >Custom Mode. |
| Memory Power Management |
| [Automatic] is suitable for most applications. [Disabled] provides maximum performance but minimum power savings. When a preset mode is selected, the low-level settings are not changeable and will be grayed out. To change the settings, choose System Settings > Operating Modes > Choose Operating Mode >Custom Mode. Note This function is only applicable for SR250 V3, ST50 V3 and ST250 V3. |
| Socket Interleave |
| Sets Socket Interleave to NUMA(Non Unified Memory Architecture) or Non-NUMA. [NUMA] means that memory is not interleaved across processors. [Non-NUMA] means that memory is interleaved across processors. Note
|
| Patrol Scrub |
| Enables or disables Patrol Scrub which proactively searches the system memory to repair correctable errors. When [Enabled] is selected, Patrol Scrub takes effect at the end of POST. |
| Memory Data Scrambling |
| Enables or disables Memory Data Scrambling. |
| ADDDC Sparing |
| Enables or disables ADDDC Sparing. ADDDC Sparing is not supported when the server has x8 DIMM, 9x4 value DIMM or memory is set to [Mirror mode] (Full or Partial). |
| Page Policy |
| [Adaptive] can improve performance for applications with a highly localized memory access pattern. [Closed] can benefit applications that access memory more randomly. |
| DRAM Post Package Repair |
| Enables or disables DRAM Post Package Repair. |
| HBM Post Package Repair |
| Enables or disables HBM Post Package Repair. Note This feature only supports HBM sku. |
| Cold Boot Fast |
| Enables or disables Cold Boot Fast. |
| AC Boot Fast |
| Enables or disables AC Boot Fast which is for AC boot only. Note This feature only applies when Cold Boot Fast is enabled. |
| Memory Test |
| Enables or disables Memory Test during normal boot. |
| Dynamic ECC Mode Selection |
| Enables or disables Dynamic ECC Mode Selection. |
| Memory Hierarchy |
| In a system with High Bandwidth Memory and regular DDR memory, Flat mode means that both HBM and DDR memory are used as a contiguous address space; Cache mode means that HBM acts as a buffer for the DDR memory. If Cache mode configuration fails or the system only has HBM, the system will fall back to Flat mode. Note Supports for HBM sku and NUMA are enabled. |
| HBM Memory Test |
| Enables or disables HBM Memory Test. Note This feature only supports HBM sku. |
| HBM PPR Type |
| Selects the post package repair type for CPU's High Bandwidth Memory in memory training phase. [PPR Disabled] does not enable PPR for High Bandwidth Memory. [Soft PPR] repairs a failing row with a spare row temporarily for current boot cycle. [Hard PPR] repairs a failing row with a spare row permanently. Note This feature only supports HBM sku. |
| HBM Refresh Mode |
| Setting HBM Refresh Mode to [Disabled] will keep factory default state. Setting it to [Double] or [Auto] can save power, lower system noise level and is useful to mitigate Rowhammer issue, but that might have a performance impact. Note This feature only supports HBM sku. |
| HBM Bank Sparing |
| Enables or disables HBM Bank Sparing. This feature is only available for Intel High Bandwidth Memory. If Bank Sparing feature is enabled, 1/16 of total High Bandwidth Memory capacity will be reserved for Bank Sparing feature. Note This feature only supports HBM sku. |
| HBM Partial Cache Line Sparing |
| Enables or disables HBM Partial Cache Line Sparing. Note This feature only supports HBM sku. |
| Mirror Configuration | N/A | Displays and configures memory mirror state. Note This feature can be configured only when ADDDC Sparing is disabled and memory population meets the requirements. |
| RAM Disk Configuration | N/A | You can press Enter to create or remove RAM disks. |
